A company called M2E Power is developing technology that will harness the kinetic movement of the human body to charge electronic devices, including cellular phones. The charging station would be a small device worn on the body. Whenever the wearer moves, such as walking or running, the movement will create and store electrical energy in a battery. The battery can then be used to charge or power a mobile device. M2E Power suggests that 6 hours worth of activity could provide 30 to 60 minutes of talk time. The company expects to have the device to market in 2009.
